The Key SEO Metrics to Monitor
Here are the 20 essential SEO metrics to evaluate and improve your performance in 2026.
1. Organic Traffic
This is the number of visitors who arrive on your site via search engines. It is the most fundamental indicator of the success of your SEO strategy.
2. Keyword Rankings
Measures the position of your pages for specific keywords in search results. Good keyword rankings are directly linked to visibility.
3. Click-Through Rate (CTR)
The percentage of users who click on your search result compared to the number of times it was displayed (impressions). A high CTR indicates an attractive title and meta description.
4. Bounce Rate
The percentage of visitors who leave your site after viewing only one page. A high bounce rate may indicate irrelevant content or a poor user experience.
5. Time on Page
The average time a user spends on a specific page. A long time suggests engaging and relevant content.
6. Pages per Session
The average number of pages viewed by a user during a single session. This indicator reflects the user's interest in the content of your site.
7. Conversion Rate
The percentage of visitors who perform a desired action (purchase, registration, quote request). This is a direct indicator of the profitability of your SEO.
8. Backlinks
Incoming links from other websites to yours. Quality backlinks are a major factor in your domain authority.
9. Domain Authority (DA) and Page Authority (PA)
These scores (developed by Moz) predict the ability of a site or page to rank on search engines. High scores are synonymous with trust.
10. Site Speed
The time it takes for your site to display completely. A fast site improves user experience and SEO ranking.
11. Core Web Vitals (CWV)
A set of web performance metrics from Google that assess user experience, including Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).
12. Mobile-Friendliness
The ability of your site to display correctly and be easily usable on mobile devices. With mobile-first indexing, this is an essential criterion.
13. Crawl Errors
Problems encountered by search engine bots when crawling your site, such as not found pages (404 errors). They must be corrected for good indexing.
14. Page Indexation
The number of pages on your site that are indexed by Google and therefore likely to appear in search results.
15. Duplicate Content
Presence of identical or very similar content on multiple pages of your site or on other sites. Duplicate content can harm your ranking.
16. Title Tag and Meta Description Optimization
The quality of your titles ( <h1> tag) and meta descriptions directly impacts your CTR and the relevance of your pages to user queries.
17. Image Optimization
Image compression, the use of descriptive alt tags, and relevant file names improve SEO and page speed.
18. Local SEO
For a local SEO agency in Brussels, local visibility is paramount. Track rankings on Google My Business and customer reviews to capture a local audience.
19. SEO Share of Voice
Measures your visibility compared to that of your competitors on a set of given keywords. This allows you to assess your market position.
20. Keyword Profitability
Evaluates which keywords generate the most conversions and revenue. This indicator is essential for refining your SEO strategy and allocating your resources effectively.
